The Ca2+ dependency of human-sperm fertilizing ability was investigated using a modified Tyrode's medium either containing 2.4 mM CaCl2 (CA medium) or with the CaCl2 replaced by SrCl2 and 0.1 mM EGTA added to chelate any residual Ca2+ ions (SREG-medium). Ten washed sperm populations incubated in eit

## Abstract The ability of caput, corpus, and cauda epididymal and vasa deferentia mouse sperm to fertilize eggs in vitro was investigated. Cauda epididymal sperm fertilized 45 of 54 ova, whereas caput and corpus sperm fertilized a negligible number of ova, thus indicating their immaturity. Vasa de
## Abstract Equal numbers of rabbit spermatozoa from the proximal cauda epididymidis and ejaculate of the same male were mixed and inseminated intravaginally. Their competitive performance in the same female was evaluated by identification of the two populations with xβirradiation marking (fertiliz
For the determination of the fertilizing life of ferret sperm in the female tract, gonadotrophin was intraperitoneally injected to induce ovulation at various times after the deposition of epididymal sperm into the uterine horns. The animals were examined 48 or 60 hours after ovulation injection to
